Hi :)
this is my first post to this forum. I am doing some study in EM
and I've come across some helpful hints on here, to help me through some problems. However i have come across a couple stumbling blocks.
if anyone could give me a couple clues to go about working these out and give me a direction to go in, it would be much appreciated. cheers in Advance.
1) how that for static fields (no time dependece and only currents of finite extent) the divergence potential is zero, i.e., [tex]\nabla\cdot[/tex]A = 0
(note the A is a vector)
2) We found that for static fields the vector potential obeys
[tex]\nabla^2[/tex] A = - [tex]\mu[/tex] oj . Show that from this equation follows that [tex]\nabla\times[/tex] B = [tex]\mu[/tex] oj
again A, B, and j are vectors.
hope my latex works..
thanks again
